In the present work exact kinetic equations describing the action of an enzyme in solution on a substrate attached to a surface have been derived in the framework of Michaelis-Menten mechanism, but without resorting to the often used steady-state approximation. The here-derived kinetic equations are casted in a workable format allowing us to introduce a simple and universal procedure for the quantitative analysis of enzyme surface kinetics valid for any kinetic situation. The results presented here should allow experimentalists studying the kinetics of enzyme action on immobilized substrates to analyze their data in a perfectly rigorous way.
